How to Evaluate AI Agents
OkBitOfConsideration · reddit · 2026-07-12
While building agents, the author kept running into scenarios where things passed manual testing but "silently broke" later, prompting them to ask the community for evaluation strategies.
Key discussion points include:
- Whether to use a fixed test set for continuous regression testing
- Sticking solely to end-to-end tests vs. also performing tool/skill-level checks
- Popular tools like DeepEval, LangSmith, Ragas, or custom-built solutions
- How robust an evaluation system needs to be before it starts providing reliable signals
